pls help‼️‼️

I. Consider the system:
3x- 3y = 3
-4x-y=-4

1) Determine the best route method: graphing, substitution, elimination) to solve the
system. Why?

2) Solve the system using each method (graphing, substitution, and elimination).

I. Consider the scenarios described for problems 1 and 2 below.

1) Set up a system of equations to address the information. Declare the meaning of all variables.

2)Solve the system using the method you think is best.

3) Conclusion:
If your answer is a decimal, tell whether you would round it? Discuss your reasoning.

Reflect on the importance of your findings in real life situations.
